Health Anxiety: Signs, Causes and How to Cope With Constant Health Worries

You notice a small lump, a flutter in your chest or a headache that won’t shift. Within minutes your mind has run through the worst possibilities. You search your symptoms, read frightening pages, check the spot again and again, then feel a brief wave of relief when a doctor says everything is fine. A day later, the doubt returns: What if they missed something?

If that sounds familiar, you may be dealing with health anxiety. It is more common than most people realise, and it is treatable. This guide explains what health anxiety is, its signs and causes, why the things we do to feel better often keep it going, and ten practical ways to cope.

What is health anxiety?

Health anxiety is an intense, ongoing worry about having, or developing, a serious illness, even when medical checks show nothing wrong or the fear is out of proportion to the evidence. It is sometimes called illness anxiety, and in older language, hypochondria (a term many now avoid because it can sound dismissive).

It is not “faking” or “attention-seeking.” The fear is real, and so is the distress. People with health anxiety are usually not reassured for long, and the worry takes up significant time and energy.

Mild health worries are very common, especially in times of illness in the news or after a loss. It becomes a problem when it is persistent, distressing and interferes with life.

Signs of health anxiety

Thoughts

• Believing normal sensations (a racing heart, muscle twitch, tingling) signal serious illness
• Repeatedly thinking about a specific disease
• Catastrophic thinking: “This headache must be a tumour”
• Difficulty tolerating uncertainty: “What if?”
• Doubting test results or doctors’ reassurance

Feelings

• Persistent worry or fear
• Panic when you notice a sensation
• Irritability, low mood or feeling on edge

Behaviours

• Body checking: examining your body for lumps, moles or changes, again and again
• Reassurance seeking: asking family, friends or doctors to confirm you are fine
• Googling symptoms for hours
• Avoidance: avoiding doctors, hospitals, medical shows or news, or anything that triggers the fear
• Frequent doctor visits, tests or second opinions
• Monitoring your pulse, blood pressure or temperature
• Avoiding activities you fear could be harmful

Physical

Anxiety itself causes real symptoms such as a pounding heart, dizziness, chest tightness, stomach upset, tingling and muscle tension. These can be misread as evidence of illness, which fuels the fear. See why anxiety feels so physical.

Why does health anxiety happen?

There is usually not a single cause. Common contributors include:

• Past experience of illness, in yourself or someone close, especially in childhood
• A recent health scare, bereavement or news of someone’s illness
• Growing up in a family that was very worried about health, or where illness was dramatic
• Anxious temperament or a tendency to worry, perfectionism or difficulty tolerating uncertainty
• Stress and life changes
• Exposure to alarming health information, including social media and online forums
• Other conditions, such as generalised anxiety, depression or obsessive-compulsive disorder

The health anxiety cycle

A well-known cognitive model of health anxiety, developed by Paul Salkovskis and colleagues, explains how the problem keeps itself going. It looks like this:

1. A trigger: a body sensation, a news story, a conversation.
2. A frightening interpretation: “This could be cancer.”
3. Anxiety: the body’s stress response kicks in, with a racing heart, tension and stomach upset.
4. More noticing: you focus on your body, making sensations feel stronger.
5. Safety behaviours: checking, Googling, seeking reassurance.
6. Short-term relief, then doubt returns, and the cycle repeats.

Seeking reassurance, in particular, is a trap. It calms you briefly, which teaches your brain that the worry needed a response, and so the urge to check comes back stronger and sooner.

Cyberchondria: the Google trap

Searching symptoms online can be useful in moderation. For people with health anxiety, though, it often backfires. Researchers who study “cyberchondria” describe how excessive health-related internet searching tends to escalate rather than reduce worry: search results often list rare, serious causes alongside common ones, and it is very difficult to stop reading. Each search offers new “what ifs.”

If you find yourself searching at 2 a.m., that is the cycle in action, not a sign of illness.

10 ways to cope with health anxiety

1. Understand the cycle

Simply knowing how health anxiety works can reduce shame and confusion. Your worry is a problem with alarm, not evidence of hidden illness. Write down your own cycle: trigger, thought, feeling, behaviour, what happened next.

2. Get a proper medical check, once, and then trust it

If you have symptoms, see a doctor and explain them, including your worry. A single, thorough assessment is sensible. But repeated tests, second opinions and re-checks often feed anxiety. Agree a plan with your doctor for what would trigger further review, and for managing anxiety. If you are told you’re healthy, practise accepting it as good news.

3. Notice and label the worry

When a health thought appears, name it: “This is health anxiety talking.” Rather than debating the details of the illness you fear, step back and describe what is happening. Naming feelings has been linked with lower emotional intensity, and it puts a little distance between you and the thought.

4. Reduce reassurance seeking, gradually

Reassurance feels like relief and works like fuel. Cut down step by step:

• Notice each time you ask someone “Do you think this is serious?”
• Delay: wait ten, then thirty minutes before asking
• Reduce how often you ask
• Tell people close to you what you are doing, so they can support you: “If I ask for reassurance, please gently remind me of the plan.”

It will feel uncomfortable at first. Anxiety rises and then falls without reassurance, which teaches your brain that you can cope.

5. Cut down body checking

Limit how often you inspect, poke, weigh or measure yourself. Decide a sensible schedule if some monitoring is medically advised, for example with a diagnosed condition, and stick to it. Constant checking makes normal sensations more noticeable.

6. Limit Googling and health forums

Set clear rules:

• No searching for symptoms when you are anxious
• Delete or block health forums that increase distress
• Use trusted sources only, briefly (for example, a national health service or a health authority), and at set times
• Consider “no-search” days

If searching is habitual, see how to stop doomscrolling for practical steps that also apply here.

7. Learn to tolerate uncertainty

Nobody can be 100 percent certain they’ll never be ill. Health anxiety demands certainty that doesn’t exist. Practise living with “maybe”: “I can’t be sure, and I can still get on with my day.” Gentle exposure helps: gradually face things you avoid, such as reading a health article without checking your body, or attending a hospital visit for a relative. Our guide to how to stop overthinking offers tools for dealing with loops.

8. Challenge catastrophic thoughts

Examine the evidence:

• What is the evidence for and against this fear?
• What is the most likely explanation? (Stress, tiredness, normal variation)
• How many times have I feared this before, and what happened?
• What would I say to a friend?
• Is there another way to see this sensation?

The aim isn’t to force positive thinking; it is to move from “worst-case certainty” to a fair, balanced view.

9. Calm your body and shift your attention

Anxiety heightens body awareness. Try:

• Slow breathing with a longer exhale, or grounding. See how to calm anxiety fast.
• Movement, such as a walk, to use up adrenaline
• Absorbing activities that turn attention outward: hobbies, conversation, work
• Regular routines for sleep, food and exercise

10. Seek psychological help

Cognitive behavioural therapy (CBT) is the best-studied treatment for health anxiety. In a large trial, CBT adapted for health anxiety reduced symptoms in patients over the long term compared with standard care. It helps you understand the cycle, test your fears and cut back on reassurance and checking. Some people benefit from medication, especially where depression or generalised anxiety is present; discuss options with a doctor.

A worked example

Suppose you feel a fluttering in your chest while watching TV.

1. Trigger: a fluttering sensation.
2. Thought: “Something is wrong with my heart.”
3. Feeling: panic, heart pounding faster.
4. Old response: check your pulse ten times, search “heart palpitations”, ask your partner for reassurance.
5. New response: name it (“health anxiety”), slow your breathing, remind yourself that palpitations are common and can be triggered by caffeine, stress or tiredness, and go back to the programme without checking.
6. Afterwards: notice that the fear rose and fell.
7. Kindness: “This is hard. I’m learning to trust my body.”

Each time you resist a safety behaviour, the anxiety loosens a little.

Supporting someone with health anxiety

• Be kind and don’t dismiss. “It’s all in your head” doesn’t help.
• Avoid endless reassurance, which feeds the cycle. Try: “I can see how worried you are. Let’s follow the plan you made.”
• Encourage professional help.
• Support routines and distraction.
• Look after yourself, since it can be draining.

When to seek help

Consider seeing a doctor or mental health professional if:

• worry about health is constant or takes up hours a day,
• it affects your work, relationships, sleep or enjoyment of life,
• you keep seeking medical tests or reassurance despite normal results,
• you avoid medical care or normal activities because of fear,
• you feel depressed, hopeless or panicky,
• you have thoughts of harming yourself.

Health anxiety is treatable, and you don’t have to cope alone. If you are in crisis, contact your local emergency number or a crisis line; in the United States you can call or text 988. See our disclaimer for more.

Frequently asked questions

Is health anxiety a real condition?

Yes. It is a recognised form of anxiety. The distress and impact on life are real, and effective treatments exist.

What is the difference between health anxiety and hypochondria?

“Hypochondria” is an older term for a similar problem. Many professionals now use “health anxiety” or “illness anxiety disorder” to describe it with less stigma.

Why does Googling symptoms make it worse?

Because searches often surface rare, alarming possibilities, and because searching is a form of reassurance seeking that keeps the cycle going.

Can health anxiety cause physical symptoms?

Yes. Anxiety can cause a pounding heart, dizziness, chest tightness, tingling and stomach problems, and these can seem to confirm the fear.

Does health anxiety go away?

For many people, it improves significantly with treatment such as CBT and with self-help techniques. It may flare in stressful times, but coping skills make it easier to manage.

How do I know if it is health anxiety or a real illness?

You can’t tell from the inside. See a doctor about symptoms, follow their advice and, if worry continues despite reassurance, talk about anxiety. Both can be addressed.

The bottom line

Health anxiety is a trap of certainty: the more you check and search for reassurance, the more you need. The way out is counterintuitive but effective: get sensible medical care, reduce checking, Googling and reassurance seeking, learn to tolerate “maybe”, and get support if you need it. Pick one safety behaviour to reduce this week, and notice that the worry rises and falls all by itself.
